Section 1: Cardiovascular and Hematologic
Disorders (Questions 1-10)
1. A 45-year-old with type 2 diabetes and heart failure with reduced
ejection fraction (HFrEF) is started on an SGLT2 inhibitor. Which of
the following best describes the mechanism by which this drug class
reduces cardiovascular mortality?
A) Increased glucagon secretion enhances cardiac contractility
B) Inhibition of sodium-glucose cotransport in the proximal tubule reduces
preload and afterload
C) Blockade of SGLT2 in the myocardium directly improves mitochondrial
function
D) Induction of ketosis increases myocardial oxygen demand and efficiency
Answer: B) Inhibition of sodium-glucose cotransport in the proximal
tubule reduces preload and afterload
Rationale: SGLT2 inhibitors work in the proximal renal tubule to reduce
glucose and sodium reabsorption, which leads to osmotic diuresis and
natriuresis. This decreases plasma volume, thereby reducing both preload
and afterload on the heart . While this class has numerous benefits, it does
,not act directly on myocardial SGLT2 transporters, nor does it primarily
improve cardiac outcomes through ketosis .

2. When assessing a patient for peripheral arterial disease (PAD),
which of the following physical examination findings is most
consistent with this condition?
A) Brownish discoloration of the skin
B) Cool extremities, absent hair, and pale skin when elevated
C) Bilateral pitting edema
D) Stasis ulcers on the medial malleolus
Answer: B) Cool extremities, absent hair, and pale skin when
elevated
Rationale: PAD is characterized by decreased arterial blood flow. Classic
findings include cool extremities, hair loss, and pallor when the extremity is
elevated (elevation pallor) . Edema, brownish discoloration, and ulcers on the
medial malleolus are characteristic of venous insufficiency, not arterial
disease .

3. A nurse practitioner is reviewing a patient's laboratory results. A
direct Coombs test is used to evaluate for which of the following
conditions?
A) Immune-mediated hemolytic anemia
B) ABO incompatibility
C) Bilirubin metabolism
D) Autoimmune hepatitis
,Answer: A) Immune-mediated hemolytic anemia
Rationale: The direct Coombs test detects antibodies bound to the surface of
red blood cells and is primarily used to diagnose immune-mediated
hemolytic anemias (e.g., autoimmune hemolytic anemia, drug-induced
hemolysis, hemolytic disease of the newborn) .

4. Which murmur characteristic is associated with mitral valve
regurgitation?
A) Holosystolic murmur radiating to the axilla, heard best at the 5th
intercostal space (ICS) mid-clavicular line (MCL)
B) Systolic ejection murmur heard best at the 2nd ICS right sternal border
(RSB)
C) Mid-systolic click
D) Diastolic rumble heard at the apex
Answer: A) Holosystolic murmur radiating to the axilla, heard best at
the 5th intercostal space (ICS) mid-clavicular line (MCL)
Rationale: Mitral regurgitation produces a holosystolic or pansystolic murmur
that is best heard at the apex (5th ICS MCL) and radiates to the axilla. A
systolic ejection murmur at the 2nd ICS RSB is characteristic of aortic
stenosis .

, 5. Which of the following ECG findings is most concerning for
hyperkalemia?
A) Peaked T waves
B) U waves
C) Wide QRS complex
D) Prolonged PR interval
Answer: A) Peaked T waves
Rationale: Peaked ("tented") T waves are one of the earliest and most
characteristic ECG changes seen in hyperkalemia. While a wide QRS complex
is also a sign of severe hyperkalemia, peaked T waves are the most classic
and frequently cited initial finding .

6. For a patient with heart failure who is being discharged, which
instruction is most appropriate regarding daily weights?
A) "I will weigh myself every morning before breakfast and after voiding."
B) "I will weigh myself once a week."
C) "I will weigh myself after dinner."
D) "I will only weigh myself if I feel short of breath."
Answer: A) "I will weigh myself every morning before breakfast and
after voiding."
Rationale: Daily weights are the most reliable indicator of fluid status in
heart failure patients. Weighing at the same time each morning, after
voiding and before breakfast, ensures consistency and helps detect early
fluid retention before symptoms worsen.
